  Serial.println("Initializing GPS...");
  gps.begin(9600);
// Initialize TensorFlow Lite model
  tflite.begin("cat_behavior_model.tflite");
}
void loop() {
  // Read GPS data
  gps.read();
  float latitude = gps.latitude;
  float longitude = gps.longitude;
  float speed = gps.speed;
// Prepare data for machine learning model
  float data[3] = {latitude, longitude, speed};
// Run inference on machine learning model
  int behavior = tflite.run(data);
// Analyze behavior
  if (behavior == 0) {
    Serial.println("Cat is sleeping");
  } else if (behavior == 1) {
    Serial.println("Cat is playing");
  } else {
    Serial.println("Cat is exploring");
  }
delay(1000);
}
```
